NEAR TERM /THROUGH TONIGHT/
A WEAK, BROAD LOW PRESSURE SYSTEM APPROACHES THE OHIO VALLEY FROM

LIGHT RAIN AND STRATUS LOCKED IN PLACE.
FOR TONIGHT, SCATTERED TO ISOLATED SHOWERS CONTINUE EAST OF A
SHORTWAVE UPPER LEVEL TROUGH AND THE ASSOCIATED SURFACE LOW.
MESOSCALE GUIDANCE DOES NOT HAVE THE VORTICITY MAX PUSHING THROUGH
UNTIL LATE OVERNIGHT/SATURDAY MORNING WHICH SUGGESTS CLOUDS AND SOME
SHOWER ACTIVITY MAY CONTINUE MOST OF THE NIGHT. FORECAST LOWS DROP A
BIT LOWER ACROSS THE NORTH WHERE THE WINDS GO MORE NORTHERLY.
HOWEVER, TEMPERATURES REMAIN WARMER SOUTH OF I-70 IN AREAS THAT
REMAIN AHEAD OF THE VORT MAX THE ENTIRE NIGHT.
SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/
A NARROW RIDGE OF HIGH PRESSURE LOOKS TO MOVE ACROSS THE OHIO VALLEY
ON SATURDAY. ALTHOUGH SOME LINGERING RAINFALL IS POSSIBLE ACROSS THE
SOUTHERN OHIO AND NORTHERN KENTUCKY ON SATURDAY MORNING, DRY
CONDITIONS ARE LIKELY FOR MOST LOCATIONS ESPECIALLY BY THE
AFTERNOON. COOL NORTHERLY WINDS LIMIT HIGHS TO THE UPPER 40S FOR
MOST LOCATIONS UNDER A MIX OF SUN AND CLOUDS.
SATURDAY NIGHT SEES WINDS QUICKLY SHIFT TOWARD THE SOUTHWEST WITH
THE APPROACH OF A WEAK TROUGH. CONDITIONS REMAIN DRY SINCE MOISTURE
AND FORCING REMAIN WEAK. FORECAST LOWS ARE IN THE MIDDLE 30S.
LONG TERM /SUNDAY THROUGH THURSDAY/
SURFACE HIGH PRESSURE BUILDS IN FROM THE WEST ON SUNDAY. MILD
CONDITIONS ALONG WITH A FAIR BIT OF SUNSHINE ARE EXPECTED. THE
SURFACE HIGH THEN MOVES OVERHEAD ON SUNDAY NIGHT CONTINUING DRY,
TRANQUIL WEATHER TO END THE WEEKEND.
ON MONDAY, THE SURFACE HIGH QUICKLY PROGRESSES EAST OF THE OHIO
VALLEY WHICH WILL ALLOW SOUTHERLY FLOW TO REDEVELOP AND UPPER LEVEL
RIDGING TO BUILD. HIGHS ON MONDAY MAKE A RUN AT 60 SOUTH OF THE OHIO
RIVER TO THE UPPER 50S FOR LOCATIONS ALONG AND NORTH OF I-70. CLOUDS
BUILD THROUGH THE DAY AS MOISTURE INCREASES. THE NEXT SYSTEM
ENCROACHES FROM THE WEST LATER IN THE DAY.
RAIN CHANCES ARRIVE MONDAY NIGHT AND PERSIST THROUGH TUESDAY NIGHT
AHEAD OF A COLD FRONT COMING IN FROM THE WEST. CURRENTLY, IT APPEARS
THAT A FIRST PUSH OF RAIN IS LIKELY WELL AHEAD OF THE FRONT ON
TUESDAY MORNING FOLLOWED BY MORE SCATTERED RAINFALL JUST AHEAD OF
THE FRONT LATER ON TUESDAY. THE HIGHEST PRECIPITATION TOTALS ARE
FORECAST TO BE ALONG AND SOUTH OF THE OHIO RIVER ACCORDING TO MEDIUM
RANGE ENSEMBLE GUIDANCE.

CONDITIONS APPEAR TO BE IN STORE FOR THE HOLIDAY.
